16v TO 8v HELP...

Finding another 16v KR motor is gettin very hard here… South Africa  So can any one tell me if i can swop my 16v powerplant from my 89 mk2 gti to go into my current project 78 mk1 3door(ok it can be done) but replace the 16v with a 2l 8v for the mk2???

thanx
any help would help more than you know

if it was me id put the 2l 8v in the mk1 instead!
to fit 2l 8v to mk2 you need to change the manifold, then all the engine loom for 8v k-jet/digifant as you'll need all the 16v bits for the mk1.  then you need a custom mk1 16v manifold/downpipe setup.

if you want to run 2.0 8v in mk2 i'd fit mk2 8v head, and digifant loom from a pre-90 GTI. 8v manifold will fit existing downpipe so zaust can be left on at least, hack up the 16v metering head feed/return lines to get the barbed fittings out of them, these fit on the 16v under car lines and the digi pipes will push straight on.

thanx for the response man… hmmmm makes sense now leaving the 16v where it is i think!!! just checking my options but I'll go with you on that! One other thing… can a 20v head from a mk4 gti or A4 work on the 8v and 16v block?? Far as i know they come standard from Turbo engines… Thanx again for the Help i appreciate it!!!

someone on golfgti forum put a 20v head on a mk2 block, i forget if it was 8v or 16v. he had it running on k-jet too! guys name is danny_p and is generally an all round legend

 yeah now you gave me some peace of mind!! U know down here in S.A… finding what you need is a HEADACHE But thanks again for the help!!! So Where do i find this guy? Dats IF he is as helping as you are!!!! Thing is im sitting with a 2l 8v powerplant… a 20v head from a A4 2l Turbo waiting for me and NOT enough know how when it comes to Bigger things lol :cry: The mk1 will be done with resto in about 4months and when she comes i wanna go full force with some power!! Sad thing is our oldskool DUBZ cant keep up with these new crap, i need some Very Wicked power!!! Any more help for me?? Thanks yet again

Thanks Jonny!! Any know how about 4stud to 5stud conversions on the mk1 to run on merc wheels??? :dontknow:

that isnt so easy, adaptors might be the way to go there? not sure what the PCD of merc wheels is

Did some research Jonny... the PCD of the merc wheel is 5X112. What can i use to make this work??Cant do porche adaptors, they not availabl down here and probly cost an arm!!The Caravelle, Passat 96, Transporter uses the same PCD far as i know?? :roll: Could the hubs perhaps be fitted on the mk1???

got me on that one! i dont think mk3 hubs fit mk1 bearing carriers, iirc the bearing is too small. mk2 type hubs can be fitted but you have to deal with bump steer as the track rod attachment is too low!

aaaah too bad! I saw theres an adaptor available for 4X100 to 5X112 but the one hole sits too close to the other… Have a look at these….




What ya think?? it'll work? looks like its actually just held to the hub with 3 studs :dontknow: how do i get it centric anyway

well three bolts was good enough for citroen
cant say either way if that would be ok or not, I'm no engineer!  Looks like it is at least hubcentric so it should centre ok.  If its centred properly there should be no shear forces on the bolts, its all about clamping pressure and friction!

HMMM TRUE i think.. but obviosly the 4th stud aint completely tightened  8O I'd probly be watching my wheels drive past me!!!
